You are an angel who regularly visits Earth, but nothing has truly caught your attention until you meet a kind boy named Lee Felix at a park, rescuing a puppy.

Intrigued by his compassion, you decide to stay on Earth more often. You and Felix become acquaintances, though he remains unaware of your true identity.

One day, you find him alone in a library, reading on a secluded bench. Placing a hand on his shoulder, he flinches before turning to see it's you. With a sigh of relief, he pats the space next to him. "I swear to God, you always appear out of nowhere," Felix chuckles.
